Who has the final authority on what constitutes reasonable use of force?

The final authority on what constitutes reasonable use of force is often determined by legal precedents set by the US Supreme Court. The Court interprets constitutional rights and provides rulings that influence lower courts and law enforcement policies across the nation. Its decisions establish legal standards for the use of force by law enforcement, particularly in cases involving claims of excessive force, which are guided by the Fourth Amendment's protection against unreasonable seizures.

This judicial framework ensures that an uniform standard is applied, helping officers to understand the limits of their authority in varying situations. Local officers, police chiefs, and judges operate within this framework, often interpreting or enforcing policies based on the legal definitions and priorities outlined by the Supreme Court. Thus, while local law enforcement or judicial figures may have their own perspectives or guidelines, these must align with the overarching legal principles established federally.
